Overview
AS-Interface 3RK1400-1MQ01-0AA4 double direct-on-line starter
24 V DC
With the K60 AS-Interface 24 V DC motor starters for the low-end
performance range up to 70 W, it is now possible to connect
24 V DC motors and the associated sensors directly to the
AS-Interface quickly and easily.

AS-Interface 24 V DC motor starter
Three different versions are available:
•
Single direct-on-line starters
(without brake and reversible quick-stop function)
•
Double direct-on-line starters
(with brake and reversible quick-stop function)
•
Reversing starters (with brake and reversible
quick-stop function)
DC motors are connected to the module using M12 plug-in
connections. The sensors and the module electronics can be
supplied from the yellow AS-Interface cable. An auxiliary voltage
(24 V DC), which is supplied via the black AS-Interface cable, is
required for supplying the outputs only.
Quick stop function
All AS-Interface 24 V DC motor starters feature a quick stop
function which can be switched on and off as required using a
switch integrated into the module. The quick stop function allows
a connected motor to be disconnected immediately using an
applied sensor signal (High). The switch for the quick stop func-
tion is located alongside the input sockets and is protected by
an M12 sealing cap.
Brake
The double direct-on-line starter and the single reversing starter
versions feature an integrated permanently set brake function,
i.e. as soon as the output signal is set to "0", the motor is braked.
Start-up using integrated buttons
Buttons integrated into the module (below the output sockets)
can be used to set the motor used. The buttons are protected by
an M12 sealing cap.
Note concerning double and reversing starters:
If an input with the quick-stop function receives a "High" signal,
the corresponding output (e.g. quick-stop input 1
output 1) is
switched off within the device (the motor is braked). The manual
key function (Key 1/2) for local operation is only permitted to be
used during "CPU Stop" in the higher-level PLC.
Note concerning single direct-on-line starters:
If an input with the quick-stop function receives a "High" signal,
the corresponding output (e.g. quick-stop input 1
output 1) is
switched off within the device (the motor coasts to a standstill
without braking). The manual key function (Key 1) for local
operation is only permitted to be used and defined during
"CPU Stop" in the higher-level PLC.
